Chemical composition and decomposition rate of plants used as green manure Scientia Agricola
Silva,Gabriela Tavares Arantes; Matos,Laudiceio Viana; Nóbrega,Pedro de Oliveira; Carneiro,Eduardo Francia; Resende,Alexander Silva de.
Productive systems in which green manure is the source of nutrients must develop more efficient ways to improve soil nutrient dynamics. A well-synchronized balance must be established between specific crop demands and supply of nutrients from decomposition. However, scientific data and information to help improve green manure management in Brazil is still insufficient. For that reason, a number of arboreal species was first chemically characterized and then subjected to decomposition analysis in order to establish a correlation between some parameters. Species were grouped together based on the similarity of chemical composition and decomposition rate. The lignin:N and (lignin+polyphenol):N ratios were found to have the greatest correlation coefficient...
